Discussion

• What challenges and complexities are associated
  with UCD in the real world?
• What similarities?
• What differences?
• What surprises?
• What implications?
• What makes it hard?
• What constitutes success of UCD?
• Where can you be flexible?
• Where do you have to stand firm?
• What options do you have for applying and
  adapting UCD methods?

Usability Maturity Discussion

• Are some companies not quite ready for usability?
• Usability higher up in the hierarchy of needs
  than functionality?
• Capability? Attitude? Readiness?
• Usability Maturity Model? Like CMM? Immaturity?
  Different Models?
• Are products from companies that have invested in
  usability worlds ahead of those from companies
  that didn't make that investment?
• Design vs. Usability
• Credit for design success?
• Is good design obvious? Simple?

5
Project Sharing

• Team discussions
• Share results of Final Design Solution
• Discuss your choice of methods and results
• Team Presentations
• Team (or Spokesperson) briefly present problem
  and solutions
• Especially challenging aspectsor surprising
  insights
• Lessons learned

6
Activity

• Draw the process of UCD
• Think on your own for a few minutes
• Pair up with someone not on your team
• Discuss and share with the class

7
Discussion of Readings

• Facilitate class discussion of topics / ideas /
  themes garnered from the online discussion,
  related to assigned readings.
• Discussion Leaders
• 1. Gülay Birand2. Thea Lehming
• 3. Ben Turner

Topic J Revisiting User-centered Design

• Driving Questions
• What activities are involved in doing
  user-centered design? What skills and knowledge
  are required to do these activities? How do you
  select the activities/methods that you will
  actually use for any specific project?
• What challenges arise in doing user-centered
  design? How can they be resolved?
• What type of information is needed to support
  user-centered design? What sources exist for
  gaining this information (i.e., the sources of
  literature)? How does a designer evaluate this
  literature? What are the benefits and costs of
  turning to these sources in order to support
  design?
• How does a designer accumulate sources of
  information so that they know where to go in
  order to become informed on a specific topic?
• Overall, how can UCD designers ensure that
  user-centered perspectives are incorporated into
  the overall design process?

Parting Thoughts

1. UCD involves REAL users
2. The purpose of UCD is two-fold
3. Improve the product/system
4. Improve the development process
5. Evaluation
6. Iteration (and re-evaluation)
7. The class project was a simplification but
8. Opportunities for UCD everywhere

User-centered Design of TC518

• Some things we learned about our users
• You give great feedback!
• The following aspects of class helped learning
  project work (hands-on), classmate experiences,
  weekly exercises, sharing independent work,
  readings, real-world examples, discussion
• Concerned about redundant class discussions,
  clarification of expectations for assignments
• Diverse group in terms of prior experience with
  design and UCD techniques professional
  experience, class experience, little/no
  experience
• We will use this user information to revise the
  design of the course.
